Human arm transmits 10mbps broadband signals

Researchers at Korea University in Seoul have transmitted data at a rate of 10 megabits per second through a person’s arm, between two electrodes placed on their skin 30 centimetres apart.

The thin, flexible electrodes use significantly less energy than a wireless link like Bluetooth. That’s because low-frequency electromagnetic waves pass through skin with little attenuation, a route that also shelters them from outside interference.
